Brontosaurus (Apatosaurus) excelsus

Brontosaurus, or Apatosaurus if you prefer, was one of the large sauropods that lived in North America at the end of the Jurassic.
In contrast to the camarasaurs and brachiosaurs that were contemporary in its range, Brontosaurus
had a long neck held low to the ground, like Diplodocus. An historically important specimen, this
massive skeleton was originally collected by a Carnegie Museum expedition and eventually given to
the State of Wyoming. This enormous TPI reproduction is based on more original fossil material
from one individual specimen than any other Apatosaurus or Brontosaurus skeleton.
